SLE Cladding Limited

This innovative Roof Tile Support system from Corus Panels & Profiles utilises the popular Trisomet profiled composite panel. Trisomet RTS offers all of the advantages associated with composites in addition to providing structural support to the traditional tiles support systems.

Trisomet RTS is a profiled composite panel with a coverwidth of 1000mm and a profile depth of 32mm. Steel facings are combined with a autohesively bonded CFC/HCFC free polyurethane or polyisocyanurate foam core. It is available in 40mm, 50mm, 60mm and 80mm core thicknesses. Lengths up to 13,000mm are available.

Trisomet is available in a range of Corus external finishes. The internal face is 0.4mm bright white polyester. CLICK HERE to see the page on TRISOMET in the Composite Cladding Section.

Properties and Performance

Structural Integrity.

Trisomet RTS is a fully ventilated system which permits airflow under the tile battens. As with all composite panels Trisomet RTS is capable of spanning considerable distances, has a high resistance to bending and good shear strength.

Acoustic Properties

Trisomet RTS has a class rating of 28db for sound transmission loss tabulated from the frequency range of 100 to 5000Hz.

Fire performance

Trisomet RTS has been tested to BS476 part 3 1975.EXT SAA (External fire exposure roof test)

Fixing Recommendations

When fixing Trisomet RTS main fasteners should be fixed at the centre of every trough at sheet ends and end laps. At the intermediates, the main fasteners should be fixed at the centre of every other trough.

Organically treated (eg. Protimised ) timber must be used for tile battens. These should be fixed at 400mm centres (maximum)

Thermal Performance

Polyisocyanurate and Polyurethane foams have exceptional insulating properties and are capable of providing the highest level of thermal insulation at the least capital cost.

These "U" values have been calculated using a thermal conductivity of 0.021W/m2. The thickness stated excludes the 32mm depth of the profile. The total panel thickness is accounted for within the U-value calculation.
